I stayed at Cindy for one evening only and used the room purely for somewhere to sleep as I moved into my own apartment the next day.
Everything described in her advertisement is available in the room. The location is an easy walk to the BTS sky train and there are lots of local food stores nearby.
Udomsuk to Asok BTS is only about 15 min by train so I'd definitely save the your money by staying at Cindy and doing a quick commute downtown.
Definitely recommended.
